Whilst I was composing this brief list, I was reminded as to why I hadn't produced it previously:
the possibility of the woods 'Book' and 'Boot' being mistaken for one-another.

However, the lack of any 'Boot Sellers' in the records leads me to have a little bit of confidence that these people were indeed selling books. I do have rather more confidence in the records for the households of Alexander Macpherson in 1871 and 1881 for it was quite usual at the time for Druggists to sell books, stationery and similar goods.

Nevertheless, we can see that bookshops were few and far between in Stornoway even at the dawn of the twentieth century, a time when there were only another eight booksellers in the whole of Ross and Cromarty and only one in Inverness-shire outside of Inverness itself, which had fourteen. Glasgow had over one hundred.
